Title: Water purification device
Inventor: HANDA FUMITAKA
IPC: B01D29/62
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To extend the intervals of overhauling of a fluidized bed type filter tank and improve the maintenance properties by disposing a fixed bed type filter tank on the upstream side of the fluidized bed type filter tank. SOLUTION: A water purification device is provided with a fixed bed type filter tank 70 on the upstream side of a fluidized bed type filter tank 2. The fixed bed type filter tank 70 is filled with filter mediums supportable by a wire mesh or a porous plate. Comparatively large suspended substances in raw water 90 are filtered physically to reduce the turbid load applied to the fluidized bed type filter tank 2. Although cloggings are generated frequently in the fixed bed type filter tank 70, the filter materials are of large particle diameter as large as supporting the filter materials by a wire mesh or a porous plate, and the inside of the fixed bed type filter tank 70 is uniformized.  Therefore, when the filter mediums flow at the time of cleaning the filter mediums and their positions are changed, no problems are generated from the viewpoint of functions, and cleaning can be carried out in a very active manner. In the case of overhauling, as the filled mediums are uniformized, labor is not so much required compared with the case of overhauling the fluidized bed type filter tank 2.

Title: Method and device for inspecting transparent substrate
Inventor: KOBAYASHI SATORU
IPC: G02B21/00
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To perform rapidly 100% inspection of appropriateness of a cross section in convex working by use of a polarization observation method. SOLUTION: First, with the use of a reference sample of transparent substrate, an analyzer 22 or a polarizer 21 is rotated so as to maximize a luminance in the center of the same cross section of the reference sample, then the luminance is computed. By inserting a 1/2-wavelength plate 24 into an optical path at an angle of 22.5 deg., an optical phase difference is shifted by 45 deg., then the luminance in the center is computed. A sinusoidal waveform passing through both points of the luminance maximum value in the center and the luminance value for the phase difference 45 deg. is computed. This sinusoidal waveform is regarded as a reference luminance distribution waveform in the same cross section of the reference sample provided by visualization of the phase difference.  Next, with the use of a crystal blank 1 to be inspected, the luminance in the same cross section of the reference sample is computed, then a luminance distribution waveform is detected. By comparing this detected luminance distribution waveform with the reference luminance distribution waveform, a thickness in the same cross section of the transparent substrate is relatively inspected.

Title: Drive circuit for three-phase induction motor and drive circuit for brushless motor
Inventor: TSUCHIYAMA YOSHIRO
IPC: H02P27/08
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To obtain a drive circuit with which sine waves having a small torque ripple are driven without using a current sensor, through which an electrification phase matched to the magnetic flux of a motor can be achieved and whose drive efficiency is enhanced. SOLUTION: A pulse-width modulation is performed with one arm of a three- phase bridge circuit 5. The remaining arms are controlled to be turned off. A phase whose voltage which becomes the lowest from among three phases turns on only a lower arm. Other phases perform a pulse-width modulation by one arm, in such a way that a potential difference from the turned-on phase becomes a prescribed value. The direction of a current is detected by a current- polarity detection circuit, on the basis of the terminal voltage of a motor 1 and on the basis of a modulation signal. When the inversion of the direction of the current is detected, the arm which performs the pulse-width modulation is turned off, and a pulse-width modulation is performed by an opposite arm.  The amplitude of a voltage is adjusted, in such a way that the zero-crossing timing of the phase of the voltage and the detecting timing of the inversion of the direction of the current becomes a fixed phase relationship.

Filed: 1987-02-05
Abstract: PURPOSE:To obtain a highly accurate current limitation protecting circuit especially for a pnp type output stage transistor(TR) by providing the protecting circuit with a current mirror circuit for detecting an output current and a constant current circuit for applying an input to the current mirror circuit. CONSTITUTION:When a load RL is in low impedance and an output current I0 is abnormally increased, a voltage drop I0R6 is increased, and the collector current of a TR Q6 constituting the current mirror together with a TR Q5 is increased. A TR Q4 is turned on by the collector current and the voltage drop of a resistor R3 and a TR Q4 sucks the driving current of the Q1, so that the Q1 is turned off. Thereby, the drive of a TR Q7 on the output stage is stopped and the Q7 is prevented from being damaged due to the increase of the output current I0. Since the output current I0 can be detected by the current mirror circuit in such constitution, the highly accurate current limitation protecting circuit redused at its dispersion and easily capable of setting an operation point can be obtained.
